SPECIFICATION forming part of Letters Patent No. 711,759, dated October21, 1902.

Application filed December 28, 1901. Serial No. 87,646. (No model.)

To ctZZ whont it may concern:

Be it known thatI, CHARLESCHMELITZEK, a citizen of the UnitedStates,residing at New Yorkcity, county and State of New York, have inventedcertain new and useful Improvements in Shelf-Supports, of which thefollowing is a specification.

My invention consists in an adjustable shelf-support, such as may beused in showcases, upon the walls of a building, or any other suitablelocation.

My invention also consists in the combination, with such shelf-supports,of a suitable show-case frame and guides, sliding shelves, drawers,850., such as are used to display jewelers ware.

The object of my invention is a shelf-support which-maybe readilyadjusted vertically and when fixed in the required position will act asa firm support for a shelf or drawer, such as is commonly employed forcarrying and displaying goods, books, the.

The accompanying drawings will serve to illustrate 'my invention, and inwhich similar letters of reference indicate like parts.

Figure 1 is a transverse section and view in perspective looking fromthe left and illustrates the employment of. one form of my improvedshelf-support in a show-case provided with sliding doors. Fig. 2 is aview in perspective looking from the right, showing one of the slottedvertical rails of a show-case having on thefront of it a guide withinwhich is a sliding block and to which the arm portion of theshelf-support shown in Fig. 3 is secured when in use. view inperspective looking from the left, showing the'rear of the arm portionof the shelf-support, the guide for the sliding shelf, and'a portion ofthe sliding shelf in dotted lines and illustrating, so far as thesliding shelf is concerned, that the under and rear portion of the shelfis provided with a stop. Fig. 4 showsa modification of myimprovedshelf-support with the slotted rail and sliding block in verticalsection and also shows by the dotted lines the manner in which the armportion of the shelf-support is introduced into the slot of the guide tosecure it to the sliding block and guide. Fig. 5 is a top view Fig. 3 isaof the construction shown in Fig. 4. Fig. 6 is a view in perspective,showing the rear of the arm of a shelf-support constructed as shown inFig. l. Fig. 7 is a view showing a further modification of my improvedshelfsupport with arm portions of two supports introduced inoppositely-situated guides and a separate supporting-piece between them.Fig. 8 is a vertical section through the transverse piece shown inFig.7, taken on the line 8 8 of Fig. 7 and looking toward the right.Fig. 9 is a view in perspective, showing the rear of the arm portion ofthe shelf-support shown in Fig.7. Fig. 10 is a detail sectional view onthe line 10 10 of Fig. 1.

In the drawings, A represents the body of the show-case, formed in theusual manner and provided in the rear with the slotted vertical rails B,between which are the hanging or sliding doors 0. Secured to the frontof each vertical rail B is a metallic guide D, formed with the angularsides E and having a slot F in its face. The guide D may be secured tothe rail by means of screws G or in any other suitable manner. LocatedWithin the guide D is a sliding block I.

J represents a removable and adjustable arm, preferably formed of metal,and consists of the vertical portion J, which is wider than the slot Fin the guide D and having the horizontal rearwardly-proj ectin g tonguesJ J which take in the sliding block I, and in case of the constructionshown in Figs. 1, 3, 4:, 5, and 6 the horizontal portion J which forms ashelf-support. In the construction shown in Figs. 1 and 3 the horizontalportion of the arm J is shown as situated below the upper tongue J onthe vertical portion J, whereas in the construction shown in Figs. 4.,5, and 6, which is especially adapted for use as a shelf-support uponthe wall of a building or in a bookcase,the upper tongue J is situatedbelow the horizontal portion J. In the construction shown in Figs. 7, 8,and 9 the vertical portion J of the arm J is formed as a separate piece,and the vertical portion is provided with a vertical slot J adapted toreceive the web of a supporting-piece K. When this construction isemployed, the guides D are arranged opposite to each other and thesupporting-piece K bridges the space between the guides.

L represents a thumb-screw by means of which the arm J may be secured tothe sliding block and guide.

It will be observed on reference to Fig. 1 that the sliding block Ifills the space intervening between the tongues J J on the arm J. Theobject of this arrangement is to facilitate the securing of the verticalportion J of the arm J to the sliding block and also to make thestructure most rigid, stable, and durable. When the vertical portion Jis to be connected, the lower tongue J is, as shown in the dotted lines,Fig. 4, introduced under the sliding block and the portion J of the armthen raised to a horizontal position, the effect of which is to causethe end of the thumbscrew L to register with the tapped. hole M in thesliding block I.

It will be understood that the vertical height of the shelf may beadjusted in any required position by securing the arm to the slidingblock and then moving the block up and down as required, and finallytightening the thumb-screw, so as to jam the vertical portion of the armJ against the face of the guide D.

I have now described all of the essential portions of my improvedshelf-support.

When the device is applied to a show-case and in order to form a supportfor a sliding shelf or drawer N, I mount upon the horizontal portion Jof the arm J ,which horizontal portion, as previously stated, may belocated below the top of the vertical portion J of the arm J, the guides0, having flanges O to engage the frame D and provided on one side, Fig.3, or on both sides, Fig. 1, with projecting horizontal portions ortenons P, on which a shelf or drawer N rests and which form runways forsuch shelf or drawer. These tenons P are cut away at the back, asindicated at Q, (see Figs. 1 and 3,) and secured to the back end at thesides of the bottom of the drawer are small check-blocks R, which actwhen the drawer is pushed forward into place between the guides O andalong the tenons or runways P to limit the forward movement of thedrawer by striking against,

the ends of the tenon P at Q.

In a show-case I may use one or more pairs of shelf-supports and slidingdrawers, ar-

the arm of the sliding block and guides in place of the thumb-screw Lmay be used.

Having thus described my invention, I claim 1. A shelf-support,comprising a slotted guide, an arm or shelf-supporting device providedwith tongues which take in the slotted guide, a slidable block lyingwithin the slotted guide and resting upon one of the tongues of saidarm, and means for securing said arm to said block and guide.

2. A shelf support comprising a slotted guide, an arm having a verticalportion and a horizontal portion, with tongues projecting rearwardlyfrom the vertical portion and which take in the slot of the guide, asliding block within said slotted guide and of sufficient length to fillthe space between the tongues projecting from the vertical portion ofthe arm engaged by both of the same, and means for securing the arm tothe block and guide.

3. A shelf supportcomprising a slotted guide, an arm having a verticalportion provided with tongues projecting rearwardly and which take inthe slot of the guide, and a horizontal portion located below the top ofthevertical portion; a sliding block within said slotted guide and ofsufficient length to fill the space between the tongues projecting fromthe vertical portion of the arm engaged by both of the same, and meansfor securing the arm to the block and guide.

4. A shelf-support comprising in its construction, a slotted guide, asliding block within the guide provided with a threaded opening, an armhaving a vertical portion with projecting tongues which take over theends of the sliding block and engage said ends respectively, said armhaving an opening which corresponds with the threaded opening in theguide, and a threaded thumbscrew engaging the openings of said slidingblock and arm.

5. In a shelf-support for show-cases, the combination of a verticalslotted rail, a slotted guide secured to said rail, a sliding block insaid guide, a removable arm provided with tongues whichtake in saidguide and engage said block, and means for securing the arm to the guideand block and adjusting its vertical position upon the rail.

6. A shelf-support, comprising a slotted guide, an arm orshelf-supporting device provided with tongues which take in the slottedguide, a slidable block lying within the slotted guide and having itsrear surface engaged with the rear Wall thereof, said block resting uponone of the tongues of said arm and engaged with the other tonguethereof, and means for securing said arm to said block and guide.

In testimony whereof I affix my signature in the presence of twowitnesses.
